Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589238, here are decompositions:

41 + 31589197 = 31589238
71 + 31589167 = 31589238
101 + 31589137 = 31589238
139 + 31589099 = 31589238
151 + 31589087 = 31589238
181 + 31589057 = 31589238
211 + 31589027 = 31589238
227 + 31589011 = 31589238

Showing the first eight; more decompositions exist.
